  "body": "B. E. Cobb (GWU), reports:\n\nUsing the ANDICAM instrument on the SMARTS 1.3m telescope at CTIO,\nwe obtained optical imaging of part of the error region of GRB 110618A\n(GCN 12077, Hurley et al.) approximately 113 hours (4.7 days)\npost-burst. Nine individual 5-minute I-band exposures were\nobtained, tiled around the center of the IPN error region\n(RA/Dec: 11h47m14s -71d41'16\").  Each image is 6'x6', so these\nimages cover approximately 0.09 square degrees, e.g. the central 6% of\nthe IPN error region.\n\nPreliminary visual comparison to the DSS reveals no new optical\nsources in the SMARTS images (limited by the slightly shallower depth\nof the DSS imaging).  This does not rule out the possibility of\nan afterglow candidate contained in a relatively bright host\ngalaxy (additional SMARTS imaging is being obtained for further\nanalysis).",
